Inhibitors of menin-MLL interaction

ABSTRACT

Disclosed herein are heterocyclic compounds that inhibit the binding of menin and MLL or MLL fusion proteins. Also described are specific inhibitors of menin-MLL interaction. Also disclosed are pharmaceutical compositions that include the compounds. Methods of using the menin-MLL inhibitors are disclosed, alone or in combination with other therapeutic agents, for the treatment of autoimmune diseases or conditions, heteroimmune diseases or conditions, cancer, including lymphoma, leukemia and other diseases or conditions dependent on menin-MLL interaction; 
                         
or a pharmaceutically acceptable salt thereof.

FIELD OF THE INVENTION

Described herein are compounds, methods of making such compounds, pharmaceutical compositions and medicaments containing such compounds, and methods of using such compounds and compositions to inhibit the activity of menin-MLL. (And may also serve as an anti-tumor agent through off-target activity by impacting other protein-protein interactions as well as kinases.)

BACKGROUND OF THE INVENTION

The Histone-lysine N-methyltransferase 2 (KMT2) family of proteins, which currently consists of at least 5 members, methylate lysine 4 on the histone H3 tails at important regulatory regions in the genome and thereby impart crucial functions through the modulation of chromatin structures and DNA accessibility (Morera, Lubbert, and Jung., Clin. Epigenetics, 8, 57-(2016)). These enzymes are known to play an important role in the regulation of gene expression during early development and hematopoiesis (Rao & Dou., Nat. Rev. Cancer, 15, 334-346 (2015)).

The human KMT2 family was initially named the mixed-lineage leukaemia (MLL) family, owing to the role of the first-found member in this disease, KMT2A which is still commonly referred to as MLL1 or MLL in routine clinical practice.

KMT2A (MLL1) is frequently found to be cytogenetically targeted in several types of leukemia (e.g. ALL and AMiL), and in those cases where balanced chromosomal translocations are found, these typically target KMT2A (MLL1) and one of over 80 translocation partner genes that have been described to date (Winters and Bernt, Front. Pediatr., 5, 4 (2017)). These chromosomal anomalies often result in the formation of fusion genes that encode fusion proteins which are believed to be causally related to the onset and/or progression of the disease.

SUMMARY OF THE INVENTION

Described herein are inhibitors of menin-MILL interaction. Also described herein are specific heterocyclic inhibitors of menin-MLL or MLL fusion proteins interaction.

Also described herein are methods for synthesizing such inhibitors, methods for using such inhibitors in the treatment of diseases (including diseases wherein inhibition of menin-MLL interaction provides therapeutic benefit to a patient having the disease). Further described are pharmaceutical compositions that include an inhibitor of menin-MLL interaction. Specifically, described herein are compounds and methods of use thereof to inhibit interaction of menin with MLL oncoproteins (e.g., MLL1, MLL2, MLL-fusion oncoproteins).

Using small molecule inhibitors of the Menin/MLL1 complex, targeting RUNX2/Menin/MLL1/MYC axis is a feasible strategy for killing p53 defective cancer cells (Shih, et al., A RUNX2-Mediated Epigenetic Regulation of the Survival of p53 Defective Cancer Cells. PLOS Genetics, https://doi.org/10.1371/journal.pgen.1005884, 2016).

In some embodiments, the disease or condition is MYC driven tumor. MYC Driven tumors and Menin/MLL1

MYC is documented to be involved broadly in many cancers, in which its expression is estimated to be elevated or deregulated in up to 70% of human cancers. High levels of MYC expression have been linked to aggressive human prostate cancer and triple negative breast cancer (Gurel et al., Mod Pathol. 2008 September; 21(9):1156-67; Palaskas et al., Cancer Res. 2011 Aug. 1; 71(15):5164-74). Experimental models of Myc-mediated tumorigenesis suggest that established tumors are addicted to Myc and that deregulated expression of Myc result in an addiction not only to Myc but also to nutrients. These Myc-induced changes provide a unique opportunity for new therapeutic strategies. Notwithstanding the fact that normal proliferating cells (stem cell compartments and immune cells) also use MYC for renewal, many studies have focused on targeting Myc for cancer therapeutics. Strategies have emerged to inhibit MYC expression, to interrupt Myc-Max dimerization, to inhibit Myc-Max DNA binding, and to interfere with key Myc target genes (Dang et al. Cell. 2012, 149(1): 22-35).

Menin's role in tumor suppression is cell-specific, Menin disruption in the liver or haematopoetic system does not result in tumors. Important to measure the concentration of the drug in endocrine tissue, liver tissue, bone marrow, and Haematopoetic.

In certain embodiments, a modulator is an inhibitor, which decreases the magnitude of one or more activities of a molecule. In certain embodiments, an inhibitor completely prevents one or more activities of a molecule. In certain embodiments, a modulator is an activator, which increases the magnitude of at least one activity of a molecule. In certain embodiments the presence of a modulator results in an activity that does not occur in the absence of the modulator.

The term “prophylactically effective amount,” as used herein, refers that amount of a composition applied to a patient that will relieve to some extent one or more of the symptoms of a disease, condition or disorder being treated. In such prophylactic applications, such amounts may depend on the patient's state of health, weight, and the like.

Compounds described herein may be prepared as a single isomer or a mixture of isomers.

In some embodiments, representative compounds of Formula (I) are prepared according to synthetic schemes depicted herein.

Further Forms of Compounds

Compounds disclosed herein have a structure of Formula (I)-(XXIIIh). It is understood that when reference is made to compounds described herein, it is meant to include compounds of any of Formula (I)-(XXIIIh) as well as to all of the specific compounds that fall within the scope of these generic formulae, unless otherwise indicated.

Compounds described herein may possess one or more stereocenters and each center may exist in the R or S configuration. Compounds presented herein include all diastereomeric, enantiomeric, and epimeric forms as well as the appropriate mixtures thereof. Stereoisomers may be obtained, if desired, by methods known in the art as, for example, the separation of stereoisomers by chiral chromatographic columns.

Diastereomeric mixtures can be separated into their individual diastereomers on the basis of their physical chemical differences by methods known, for example, by chromatography and/or fractional crystallization. In some embodiments, enantiomers can be separated by chiral chromatographic columns. In some embodiments, enantiomers can be separated by converting the enantiomeric mixture into a diastereomeric mixture by reaction with an appropriate optically active compound (e.g., alcohol), separating the diastereomers and converting (e.g., hydrolyzing) the individual diastereomers to the corresponding pure enantiomers. All such isomers, including diastereomers, enantiomers, and mixtures thereof are considered as part of the compositions described herein.

Methods and formulations described herein include the use of N-oxides, crystalline forms (also known as polymorphs), or pharmaceutically acceptable salts of compounds described herein, as well as active metabolites of these compounds having the same type of activity. In some situations, compounds may exist as tautomers. All tautomers are included within the scope of the compounds presented herein. In addition, compounds described herein can exist in unsolvated as well as solvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like. Solvated forms of compounds presented herein are also considered to be disclosed herein.

Compounds of any of Formula (I)-(XXIIIh) in unoxidized form can be prepared from N-oxides of compounds of any of Formula (I)-(XXIIIh) by treating with a reducing agent, such as, but not limited to, sulfur, sulfur dioxide, triphenyl phosphine, lithium borohydride, sodium borohydride, phosphorus trichloride, tribromide, or the like in a suitable inert organic solvent, such as, but not limited to, acetonitrile, ethanol, aqueous dioxane, or the like at 0 to 80° C.

In some embodiments, compounds described herein are prepared as prodrugs. A “prodrug” refers to an agent that is converted into the parent drug in vivo. Prodrugs are often useful because, in some situations, they may be easier to administer than the parent drug. They may, for instance, be bioavailable by oral administration whereas the parent is not. The prodrug may also have improved solubility in pharmaceutical compositions over the parent drug. An example, without limitation, of a prodrug would be a compound described herein, which is administered as an ester (the “prodrug”) to facilitate transmittal across a cell membrane where water solubility is detrimental to mobility but which then is metabolically hydrolyzed to the carboxylic acid, the active entity, once inside the cell where water-solubility is beneficial. A further example of a prodrug might be a short peptide (polyaminoacid) bonded to an acid group where the peptide is metabolized to reveal the active moiety. In certain embodiments, upon in vivo administration, a prodrug is chemically converted to the biologically, pharmaceutically or therapeutically active form of the compound. In certain embodiments, a prodrug is enzymatically metabolized by one or more steps or processes to the biologically, pharmaceutically or therapeutically active form of the compound. To produce a prodrug, a pharmaceutically active compound is modified such that the active compound will be regenerated upon in vivo administration. The prodrug can be designed to alter the metabolic stability or the transport characteristics of a drug, to mask side effects or toxicity, to improve the flavor of a drug or to alter other characteristics or properties of a drug. By virtue of knowledge of pharmacodynamic processes and drug metabolism in vivo, those of skill in this art, once a pharmaceutically active compound is known, can design prodrugs of the compound. (see, for example, Nogrady (1985) Medicinal Chemistry A Biochemical Approach, Oxford University Press, New York, pages 388-392; Silverman (1992), The Organic Chemistry of Drug Design and Drug Action, Academic Press, Inc., San Diego, pages 352-401, Saulnier et al., (1994), Bioorganic and Medicinal Chemistry Letters, Vol. 4, p. 1985).

Prodrug forms of the herein described compounds, wherein the prodrug is metabolized in vivo to produce a derivative as set forth herein are included within the scope of the claims. In some cases, some of the herein-described compounds may be a prodrug for another derivative or active compound.

Prodrugs are often useful because, in some situations, they may be easier to administer than the parent drug. They may, for instance, be bioavailable by oral administration whereas the parent is not. The prodrug may also have improved solubility in pharmaceutical compositions over the parent drug. Prodrugs may be designed as reversible drug derivatives, for use as modifiers to enhance drug transport to site-specific tissues. In some embodiments, the design of a prodrug increases the effective water solubility. See, e.g., Fedorak et al., Am. J. Physiol., 269:G210-218 (1995); McLoed et al., Gastroenterol, 106:405-413 (1994); Hochhaus et al., Biomed. Chrom., 6:283-286 (1992); J. Larsen and H. Bundgaard, Int. J. Pharmaceutics, 37, 87 (1987); J. Larsen et al., Int. J. Pharmaceutics, 47, 103 (1988); Sinkula et al., J. Pharm. Sci., 64:181-210 (1975); T. Higuchi and V. Stella, Pro-drugs as Novel Delivery Systems, Vol. 14 of the A.C.S. Symposium Series; and Edward B.

Sites on the aromatic ring portion of compounds of any of Formula (I)-(XXIIIh) can be susceptible to various metabolic reactions, therefore incorporation of appropriate substituents on the aromatic ring structures, such as, by way of example only, halogens can reduce, minimize or eliminate this metabolic pathway.

Compounds described herein include isotopically-labeled compounds, which are identical to those recited in the various formulas and structures presented herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into the present compounds include isotopes of hydrogen, carbon, nitrogen, oxygen, fluorine and chlorine, such as ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ¹O, ³⁵S, ¹⁸F, ³⁶Cl, respectively. Certain isotopically-labeled compounds described herein, for example those into which radioactive isotopes such as ³H and ¹⁴C are incorporated, are useful in drug and/or substrate tissue distribution assays. Further, substitution with isotopes such as deuterium, i.e., ²H, can afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements.

In additional or some embodiments, the compounds described herein are metabolized upon administration to an organism in need to produce a metabolite that is then used to produce a desired effect, including a desired therapeutic effect.

Additionally, pharmaceutical compositions described herein may be administered as a single capsule or in multiple capsule dosage form. In some embodiments, the pharmaceutical composition is administered in two, or three, or four, capsules or tablets.

In some embodiments, solid dosage forms, e.g., tablets, effervescent tablets, and capsules, are prepared by mixing particles of a compound of any of Formula (I)-(XXIIIh) with one or more pharmaceutical excipients to form a bulk blend composition. When referring to these bulk blend compositions as homogeneous, it is meant that the particles of the compound of any of Formula (I)-(XXIIIh) are dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms, such as tablets, pills, and capsules. The individual unit dosages may also include film coatings, which disintegrate upon oral ingestion or upon contact with diluent. These formulations can be manufactured by conventional pharmacological techniques.

Conventional pharmacological techniques include, e.g., one or a combination of methods: (1) dry mixing, (2) direct compression, (3) milling, (4) dry or non-aqueous granulation, (5) wet granulation, or (6) fusion. See, e.g., Lachman et al., The Theory and Practice of Industrial Pharmacy (1986). Other methods include, e.g., spray drying, pan coating, melt granulation, granulation, fluidized bed spray drying or coating (e.g., wurster coating), tangential coating, top spraying, tableting, extruding and the like.

The pharmaceutical solid dosage forms described herein can include a compound described herein and one or more pharmaceutically acceptable additives such as a compatible carrier, binder, filling agent, suspending agent, flavoring agent, sweetening agent, disintegrating agent, dispersing agent, surfactant, lubricant, colorant, diluent, solubilizer, moistening agent, plasticizer, stabilizer, penetration enhancer, wetting agent, anti-foaming agent, antioxidant, preservative, or one or more combination thereof. In some embodiments, using standard coating procedures, such as those described in Remington's Pharmaceutical Sciences, 20th Edition (2000), a film coating is provided around the formulation of the compound of any of Formula (I)-(XXIIIh). In some embodiments, some or all of the particles of the compound of any of Formula (I)-(XXIIIh) are coated.

Thus, the above-listed additives should be taken as merely exemplary, and not limiting, of the types of additives that can be included in solid dosage forms described herein. The amounts of such additives can be readily determined by one skilled in the art, according to the particular properties desired.

In some embodiments, one or more layers of the pharmaceutical composition are plasticized. Illustratively, a plasticizer is generally a high boiling point solid or liquid. Suitable plasticizers can be added from about 0.01% to about 50% by weight (w/w) of the coating composition. Plasticizers include, but are not limited to, diethyl phthalate, citrate esters, polyethylene glycol, glycerol, acetylated glycerides, triacetin, polypropylene glycol, polyethylene glycol, triethyl citrate, dibutyl sebacate, stearic acid, stearol, stearate, and castor oil.

In various embodiments, compressed tablets which are designed to dissolve in the mouth will include one or more flavoring agents. In some embodiments, the compressed tablets will include a film surrounding the final compressed tablet. In some embodiments, the film coating can provide a delayed release of the compound of of any of Formula (I)-(XXIIIh) from the formulation. In some embodiments, the film coating aids in patient compliance (e.g., Opadry® coatings or sugar coating). Film coatings including Opadry® typically range from about 1% to about 3% of the tablet weight. In some embodiments, the compressed tablets include one or more excipients.

A capsule may be prepared, for example, by placing the bulk blend of the formulation of the compound of any of Formula (I)-(XXIIIh), described above, inside of a capsule. In some embodiments, the formulations (non-aqueous suspensions and solutions) are placed in a soft gelatin capsule. In some embodiments, the formulations are placed in standard gelatin capsules or non-gelatin capsules such as capsules comprising HPMC. In some embodiments, the formulation is placed in a sprinkle capsule, wherein the capsule may be swallowed whole or the capsule may be opened and the contents sprinkled on food prior to eating. In some embodiments, the therapeutic dose is split into multiple (e.g., two, three, or four) capsules. In some embodiments, the entire dose of the formulation is delivered in a capsule form.

In various embodiments, the particles of the compound of any of Formula (I)-(XXIIIh) and one or more excipients are dry blended and compressed into a mass, such as a tablet, having a hardness sufficient to provide a pharmaceutical composition that substantially disintegrates within less than about 30 minutes, less than about 35 minutes, less than about 40 minutes, less than about 45 minutes, less than about 50 minutes, less than about 55 minutes, or less than about 60 minutes, after oral administration, thereby releasing the formulation into the gastrointestinal fluid.

In some embodiments, dosage forms may include microencapsulated formulations. In some embodiments, one or more other compatible materials are present in the microencapsulation material. Exemplary materials include, but are not limited to, pH modifiers, erosion facilitators, anti-foaming agents, antioxidants, flavoring agents, and carrier materials such as binders, suspending agents, disintegration agents, filling agents, surfactants, solubilizers, stabilizers, lubricants, wetting agents, and diluents.

Materials useful for the microencapsulation described herein include materials compatible with compounds of any of Formula (I)-(XXIIIh) which sufficiently isolate the compound of any of Formula (I)-(XXIIIh) from other non-compatible excipients. Materials compatible with compounds of any of Formula (I)-(XXIIIh) are those that delay the release of the compounds of of any of Formula (I)-(XXIIIh), in vivo.

In some embodiments, the microencapsulating material useful for delaying the release of the pharmaceutical compositions is from the USP or the National Formulary (NF). In some embodiments, the microencapsulation material is Klucel. In some embodiments, the microencapsulation material is methocel.

Microencapsulated compounds of any of Formula (I)-(XXIIIh) may be formulated by methods known by one of ordinary skill in the art. Such known methods include, e.g., spray drying processes, spinning disk-solvent processes, hot melt processes, spray chilling methods, fluidized bed, electrostatic deposition, centrifugal extrusion, rotational suspension separation, polymerization at liquid-gas or solid-gas interface, pressure extrusion, or spraying solvent extraction bath. In addition to these, several chemical techniques, e.g., complex coacervation, solvent evaporation, polymer-polymer incompatibility, interfacial polymerization in liquid media, in situ polymerization, in-liquid drying, and desolvation in liquid media could also be used. Furthermore, other methods such as roller compaction, extrusion/spheronization, coacervation, or nanoparticle coating may also be used.

In some embodiments, the particles of compounds of any of Formula (I)-(XXIIIh) are microencapsulated prior to being formulated into one of the above forms. In still some embodiments, some or most of the particles are coated prior to being further formulated by using standard coating procedures, such as those described in Remington's Pharmaceutical Sciences, 20th Edition (2000).

In some embodiments, the solid dosage formulations of the compounds of any of Formula (I)-(XXIIIh) are plasticized (coated) with one or more layers. Illustratively, a plasticizer is generally a high boiling point solid or liquid. Suitable plasticizers can be added from about 0.01% to about 50% by weight (w/w) of the coating composition. Plasticizers include, but are not limited to, diethyl phthalate, citrate esters, polyethylene glycol, glycerol, acetylated glycerides, triacetin, polypropylene glycol, polyethylene glycol, triethyl citrate, dibutyl sebacate, stearic acid, stearol, stearate, and castor oil.

In some embodiments, a powder including the formulations with a compound of any of Formula (I)-(XXIIIh), described herein, may be formulated to include one or more pharmaceutical excipients and flavors. Such a powder may be prepared, for example, by mixing the formulation and optional pharmaceutical excipients to form a bulk blend composition. Additional embodiments also include a suspending agent and/or a wetting agent. This bulk blend is uniformly subdivided into unit dosage packaging or multi-dosage packaging units.

In still some embodiments, effervescent powders are also prepared in accordance with the present disclosure. Effervescent salts have been used to disperse medicines in water for oral administration. Effervescent salts are granules or coarse powders containing a medicinal agent in a dry mixture, usually composed of sodium bicarbonate, citric acid and/or tartaric acid. When salts of the compositions described herein are added to water, the acids and the base react to liberate carbon dioxide gas, thereby causing “effervescence.” Examples of effervescent salts include, e.g., the following ingredients: sodium bicarbonate or a mixture of sodium bicarbonate and sodium carbonate, citric acid and/or tartaric acid. Any acid-base combination that results in the liberation of carbon dioxide can be used in place of the combination of sodium bicarbonate and citric and tartaric acids, as long as the ingredients were suitable for pharmaceutical use and result in a pH of about 6.0 or higher.

In some embodiments, the formulations described herein, which include a compound of Formula (A), are solid dispersions. Methods of producing such solid dispersions are known in the art and include, but are not limited to, for example, U.S. Pat. Nos. 4,343,789, 5,340,591, 5,456,923, 5,700,485, 5,723,269, and U.S. Pub. Appl 2004/0013734, each of which is specifically incorporated by reference. In some embodiments, the formulations described herein are solid solutions. Solid solutions incorporate a substance together with the active agent and other excipients such that heating the mixture results in dissolution of the drug and the resulting composition is then cooled to provide a solid blend which can be further formulated or directly added to a capsule or compressed into a tablet. Methods of producing such solid solutions are known in the art and include, but are not limited to, for example, U.S. Pat. Nos. 4,151,273, 5,281,420, and 6,083,518, each of which is specifically incorporated by reference.

The pharmaceutical solid oral dosage forms including formulations described herein, which include a compound of any of Formula (I)-(XXIIIh) can be further formulated to provide a controlled release of the compound of Formula (A). Controlled release refers to the release of the compound of any of Formula (I)-(XXIIIh) from a dosage form in which it is incorporated according to a desired profile over an extended period of time. Controlled release profiles include, for example, sustained release, prolonged release, pulsatile release, and delayed release profiles. In contrast to immediate release compositions, controlled release compositions allow delivery of an agent to a subject over an extended period of time according to a predetermined profile. Such release rates can provide therapeutically effective levels of agent for an extended period of time and thereby provide a longer period of pharmacologic response while minimizing side effects as compared to conventional rapid release dosage forms. Such longer periods of response provide for many inherent benefits that are not achieved with the corresponding short acting, immediate release preparations.

In some embodiments, the solid dosage forms described herein can be formulated as enteric coated delayed release oral dosage forms, i.e., as an oral dosage form of a pharmaceutical composition as described herein which utilizes an enteric coating to affect release in the small intestine of the gastrointestinal tract. The enteric coated dosage form may be a compressed or molded or extruded tablet/mold (coated or uncoated) containing granules, powder, pellets, beads or particles of the active ingredient and/or other composition components, which are themselves coated or uncoated. The enteric coated oral dosage form may also be a capsule (coated or uncoated) containing pellets, beads or granules of the solid carrier or the composition, which are themselves coated or uncoated.

The term “delayed release” as used herein refers to the delivery so that the release can be accomplished at some generally predictable location in the intestinal tract more distal to that which would have been accomplished if there had been no delayed release alterations. In some embodiments the method for delay of release is coating. Any coatings should be applied to a sufficient thickness such that the entire coating does not dissolve in the gastrointestinal fluids at pH below about 5, but does dissolve at pH about 5 and above. It is expected that any anionic polymer exhibiting a pH-dependent solubility profile can be used as an enteric coating in the methods and compositions described herein to achieve delivery to the lower gastrointestinal tract. In some embodiments the polymers described herein are anionic carboxylic polymers. In some embodiments, the polymers and compatible mixtures thereof, and some of their properties, include, but are not limited to:

Shellac, also called purified lac, a refined product obtained from the resinous secretion of an insect. This coating dissolves in media of pH >7;

Acrylic polymers. The performance of acrylic polymers (primarily their solubility in biological fluids) can vary based on the degree and type of substitution. Examples of suitable acrylic polymers include methacrylic acid copolymers and ammonium methacrylate copolymers.

The Eudragit series E, L, S, RL, RS and NE (Rohm Pharma) are available as solubilized in organic solvent, aqueous dispersion, or dry powders. The Eudragit series RL, NE, and RS are insoluble in the gastrointestinal tract but are permeable and are used primarily for colonic targeting. The Eudragit series E dissolve in the stomach. The Eudragit series L, L-30D and S are insoluble in stomach and dissolve in the intestine.

Cellulose Derivatives. Examples of suitable cellulose derivatives are: ethyl cellulose; reaction mixtures of partial acetate esters of cellulose with phthalic anhydride. The performance can vary based on the degree and type of substitution. Cellulose acetate phthalate (CAP) dissolves in pH >6. Aquateric (FMC) is an aqueous based system and is a spray dried CAP psuedolatex with particles <1 μm. Other components in Aquateric can include pluronics, Tweens, and acetylated monoglycerides. Other suitable cellulose derivatives include: cellulose acetate trimellitate (Eastman); methylcellulose (Pharmacoat, Methocel); hydroxypropylmethyl cellulose phthalate (HPMCP); hydroxypropylmethyl cellulose succinate (HPMCS); and hydroxypropylmethylcellulose acetate succinate (e.g., AQOAT (Shin Etsu)). The performance can vary based on the degree and type of substitution. For example, HPMCP such as, HP-50, HP-55, HP-55S, HP-55F grades are suitable. The performance can vary based on the degree and type of substitution. For example, suitable grades of hydroxypropylmethylcellulose acetate succinate include, but are not limited to, AS-LG (LF), which dissolves at pH 5, AS-MG (MF), which dissolves at pH 5.5, and AS-HG (HF), which dissolves at higher pH. These polymers are offered as granules, or as fine powders for aqueous dispersions;

Poly Vinyl Acetate Phthalate (PVAP). PVAP dissolves in pH >5, and it is much less permeable to water vapor and gastric fluids.

In some embodiments, the coating can, and usually does, contain a plasticizer and possibly other coating excipients such as colorants, talc, and/or magnesium stearate, which are well known in the art. Suitable plasticizers include triethyl citrate (Citroflex 2), triacetin (glyceryl triacetate), acetyl triethyl citrate (Citroflec A2), Carbowax 400 (polyethylene glycol 400), diethyl phthalate, tributyl citrate, acetylated monoglycerides, glycerol, fatty acid esters, propylene glycol, and dibutyl phthalate. In particular, anionic carboxylic acrylic polymers usually will contain 10-25% by weight of a plasticizer, especially dibutyl phthalate, polyethylene glycol, triethyl citrate and triacetin. Conventional coating techniques such as spray or pan coating are employed to apply coatings. The coating thickness must be sufficient to ensure that the oral dosage form remains intact until the desired site of topical delivery in the intestinal tract is reached.

Colorants, detackifiers, surfactants, antifoaming agents, lubricants (e.g., carnuba wax or PEG) may be added to the coatings besides plasticizers to solubilize or disperse the coating material, and to improve coating performance and the coated product.

In some embodiments, the formulations described herein, which include a compound of Formula (A), are delivered using a pulsatile dosage form. A pulsatile dosage form is capable of providing one or more immediate release pulses at predetermined time points after a controlled lag time or at specific sites. Pulsatile dosage forms including the formulations described herein, which include a compound of any of Formula (I)-(XXIIIh) may be administered using a variety of pulsatile formulations known in the art. For example, such formulations include, but are not limited to, those described in U.S. Pat. Nos. 5,011,692, 5,017,381, 5,229,135, and 5,840,329, each of which is specifically incorporated by reference. Other pulsatile release dosage forms suitable for use with the present formulations include, but are not limited to, for example, U.S. Pat. Nos. 4,871,549, 5,260,068, 5,260,069, 5,508,040, 5,567,441 and 5,837,284, all of which are specifically incorporated by reference. In some embodiments, the controlled release dosage form is pulsatile release solid oral dosage form including at least two groups of particles, (i.e. multiparticulate) each containing the formulation described herein. The first group of particles provides a substantially immediate dose of the compound of any of Formula (I)-(XXIIIh) upon ingestion by a mammal. The first group of particles can be either uncoated or include a coating and/or sealant. The second group of particles includes coated particles, which includes from about 2% to about 75%, from about 2.5% to about 70%, or from about 40% to about 70%, by weight of the total dose of the compound of any of Formula (I)-(XXIIIh) in said formulation, in admixture with one or more binders. The coating includes a pharmaceutically acceptable ingredient in an amount sufficient to provide a delay of from about 2 hours to about 7 hours following ingestion before release of the second dose. Suitable coatings include one or more differentially degradable coatings such as, by way of example only, pH sensitive coatings (enteric coatings) such as acrylic resins (e.g., Eudragit® EPO, Eudragit® L30D-55, Eudragit® FS 30D Eudragit® L100-55, Eudragit® L100, Eudragit® S100, Eudragit® RD100, Eudragit® E100, Eudragit® L12.5, Eudragit® 512.5, and Eudragit® NE30D, Eudragit® NE 40D©) either alone or blended with cellulose derivatives, e.g., ethylcellulose, or non-enteric coatings having variable thickness to provide differential release of the formulation that includes a compound of any of Formula (I).

Many other types of controlled release systems known to those of ordinary skill in the art and are suitable for use with the formulations described herein. Examples of such delivery systems include, e.g., polymer-based systems, such as polylactic and polyglycolic acid, plyanhydrides and polycaprolactone; porous matrices, nonpolymer-based systems that are lipids, including sterols, such as cholesterol, cholesterol esters and fatty acids, or neutral fats, such as mono-, di- and triglycerides; hydrogel release systems; silastic systems; peptide-based systems; wax coatings, bioerodible dosage forms, compressed tablets using conventional binders and the like. See, e.g., Liberman et al., Pharmaceutical Dosage Forms, 2 Ed., Vol. 1, pp. 209-214 (1990); Singh et al., Encyclopedia ofPharmaceutical Technology, 2^(nd) Ed., pp. 751-753 (2002); U.S. Pat. Nos. 4,327,725, 4,624,848, 4,968,509, 5,461,140, 5,456,923, 5,516,527, 5,622,721, 5,686,105, 5,700,410, 5,977,175, 6,465,014 and 6,932,983, each of which is specifically incorporated by reference.

In some embodiments, pharmaceutical compositions are provided that include particles of the compounds of any of Formula (I)-(XXIIIh), described herein and at least one dispersing agent or suspending agent for oral administration to a subject. The formulations may be a powder and/or granules for suspension, and upon admixture with water, a substantially uniform suspension is obtained.

Liquid formulation dosage forms for oral administration can be aqueous suspensions selected from the group including, but not limited to, pharmaceutically acceptable aqueous oral dispersions, emulsions, solutions, elixirs, gels, and syrups. See, e.g., Singh et al., Encyclopedia of Pharmaceutical Technology, 2^(nd) Ed., pp. 754-757 (2002). In addition to the particles of compound of Formula (A), the liquid dosage forms may include additives, such as: (a) disintegrating agents; (b) dispersing agents; (c) wetting agents; (d) at least one preservative, (e) viscosity enhancing agents, (f) at least one sweetening agent, and (g) at least one flavoring agent. In some embodiments, the aqueous dispersions can further include a crystalline inhibitor.

The aqueous suspensions and dispersions described herein can remain in a homogenous state, as defined in The USP Pharmacists' Pharmacopeia (2005 edition, chapter 905), for at least 4 hours. The homogeneity should be determined by a sampling method consistent with regard to determining homogeneity of the entire composition. In some embodiments, an aqueous suspension can be re-suspended into a homogenous suspension by physical agitation lasting less than 1 minute. In some embodiments, an aqueous suspension can be re-suspended into a homogenous suspension by physical agitation lasting less than 45 seconds.

In some embodiments, the pharmaceutical compositions described herein can be self-emulsifying drug delivery systems (SEDDS). Emulsions are dispersions of one immiscible phase in another, usually in the form of droplets. Generally, emulsions are created by vigorous mechanical dispersion. SEDDS, as opposed to emulsions or microemulsions, spontaneously form emulsions when added to an excess of water without any external mechanical dispersion or agitation. An advantage of SEDDS is that only gentle mixing is required to distribute the droplets throughout the solution. Additionally, water or the aqueous phase can be added just prior to administration, which ensures stability of an unstable or hydrophobic active ingredient. Thus, the SEDDS provides an effective delivery system for oral and parenteral delivery of hydrophobic active ingredients. SEDDS may provide improvements in the bioavailability of hydrophobic active ingredients. Methods of producing self-emulsifying dosage forms are known in the art and include, but are not limited to, for example, U.S. Pat. Nos. 5,858,401, 6,667,048, and 6,960,563, each of which is specifically incorporated by reference.

It is to be appreciated that there is overlap between the above-listed additives used in the aqueous dispersions or suspensions described herein, since a given additive is often classified differently by different practitioners in the field, or is commonly used for any of several different functions. Thus, the above-listed additives should be taken as merely exemplary, and not limiting, of the types of additives that can be included in formulations described herein. The amounts of such additives can be readily determined by one skilled in the art, according to the particular properties desired.

Intranasal Formulations

Intranasal formulations are known in the art and are described in, for example, U.S. Pat. Nos. 4,476,116, 5,116,817 and 6,391,452, each of which is specifically incorporated by reference. Formulations that include a compound of any of Formula (I)-(XXIIIh) which are prepared according to these and other techniques well-known in the art are prepared as solutions in saline, employing benzyl alcohol or other suitable preservatives, fluorocarbons, and/or other solubilizing or dispersing agents known in the art. See, for example, Ansel, H. C. et al., Pharmaceutical Dosage Forms and Drug Delivery Systems, Sixth Ed. (1995). Preferably these compositions and formulations are prepared with suitable nontoxic pharmaceutically acceptable ingredients. These ingredients are known to those skilled in the preparation of nasal dosage forms and some of these can be found in REMINGTON: THE SCIENCE AND PRACTICE OF PHARMACY, 21st edition, 2005, a standard reference in the field. The choice of suitable carriers is highly dependent upon the exact nature of the nasal dosage form desired, e.g., solutions, suspensions, ointments, or gels. Nasal dosage forms generally contain large amounts of water in addition to the active ingredient. Minor amounts of other ingredients such as pH adjusters, emulsifiers or dispersing agents, preservatives, surfactants, gelling agents, or buffering and other stabilizing and solubilizing agents may also be present. The nasal dosage form should be isotonic with nasal secretions.

For administration by inhalation, the compounds of any of Formula (I)-(XXIIIh), described herein may be in a form as an aerosol, a mist or a powder. Pharmaceutical compositions described herein are conveniently delivered in the form of an aerosol spray presentation from pressurized packs or a nebuliser, with the use of a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide or other suitable gas. In the case of a pressurized aerosol, the dosage unit may be determined by providing a valve to deliver a metered amount. Capsules and cartridges of, such as, by way of example only, gelatin for use in an inhaler or insufflator may be formulated containing a powder mix of the compound described herein and a suitable powder base such as lactose or starch.

Buccal Formulations

Buccal formulations that include compounds of any of Formula (I)-(XXIIIh) may be administered using a variety of formulations known in the art. For example, such formulations include, but are not limited to, U.S. Pat. Nos. 4,229,447, 4,596,795, 4,755,386, and 5,739,136, each of which is specifically incorporated by reference. In addition, the buccal dosage forms described herein can further include a bioerodible (hydrolysable) polymeric carrier that also serves to adhere the dosage form to the buccal mucosa. The buccal dosage form is fabricated so as to erode gradually over a predetermined time period, wherein the delivery of the compound of any of Formula (I)-(XXIIIh), is provided essentially throughout. Buccal drug delivery, as will be appreciated by those skilled in the art, avoids the disadvantages encountered with oral drug administration, e.g., slow absorption, degradation of the active agent by fluids present in the gastrointestinal tract and/or first-pass inactivation in the liver. With regard to the bioerodible (hydrolysable) polymeric carrier, it will be appreciated that virtually any such carrier can be used, so long as the desired drug release profile is not compromised, and the carrier is compatible with the compound of any of Formula (I), (Ia)-(Ic), (IIa)-(IId), (IIIa)-(IIIh), (IVa)-(IVd), (Va)-(Vd), (VIa)-(VIh), (VIIa)-(VIId), (VIIIa)-(VIIIh), (IXa)-(IXd), (Xa)-(Xh), (XIa)-(XIj) or (XIIa)-(XIIh), and any other components that may be present in the buccal dosage unit. Generally, the polymeric carrier comprises hydrophilic (water-soluble and water-swellable) polymers that adhere to the wet surface of the buccal mucosa. Examples of polymeric carriers useful herein include acrylic acid polymers and co, e.g., those known as “carbomers” (Carbopol®, which may be obtained from B. F. Goodrich, is one such polymer). Other components may also be incorporated into the buccal dosage forms described herein include, but are not limited to, disintegrants, diluents, binders, lubricants, flavoring, colorants, preservatives, and the like. For buccal or sublingual administration, the compositions may take the form of tablets, lozenges, or gels formulated in a conventional manner.

Transdermal Formulations

Transdermal formulations described herein may be administered using a variety of devices which have been described in the art. For example, such devices include, but are not limited to, U.S. Pat. Nos. 3,598,122, 3,598,123, 3,710,795, 3,731,683, 3,742,951, 3,814,097, 3,921,636, 3,972,995, 3,993,072, 3,993,073, 3,996,934, 4,031,894, 4,060,084, 4,069,307, 4,077,407, 4,201,211, 4,230,105, 4,292,299, 4,292,303, 5,336,168, 5,665,378, 5,837,280, 5,869,090, 6,923,983, 6,929,801 and 6,946,144, each of which is specifically incorporated by reference in its entirety.

The transdermal dosage forms described herein may incorporate certain pharmaceutically acceptable excipients which are conventional in the art. In some embodiments, the transdermal formulations described herein include at least three components: (1) a formulation of a compound of any of Formula (I); (2) a penetration enhancer; and (3) an aqueous adjuvant. In addition, transdermal formulations can include additional components such as, but not limited to, gelling agents, creams and ointment bases, and the like. In some embodiments, the transdermal formulation can further include a woven or non-woven backing material to enhance absorption and prevent the removal of the transdermal formulation from the skin. In some embodiments, the transdermal formulations described herein can maintain a saturated or supersaturated state to promote diffusion into the skin.

Formulations suitable for transdermal administration of compounds described herein may employ transdermal delivery devices and transdermal delivery patches and can be lipophilic emulsions or buffered, aqueous solutions, dissolved and/or dispersed in a polymer or an adhesive. Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents. Still further, transdermal delivery of the compounds described herein can be accomplished by means of iontophoretic patches and the like. Additionally, transdermal patches can provide controlled delivery of the compounds of any of Formula (I)-(XXIIIh). The rate of absorption can be slowed by using rate-controlling membranes or by trapping the compound within a polymer matrix or gel. Conversely, absorption enhancers can be used to increase absorption. An absorption enhancer or carrier can include absorbable pharmaceutically acceptable solvents to assist passage through the skin. For example, transdermal devices are in the form of a bandage comprising a backing member, a reservoir containing the compound optionally with carriers, optionally a rate controlling barrier to deliver the compound to the skin of the host at a controlled and predetermined rate over a prolonged period of time, and means to secure the device to the skin.

Injectable Formulations

Formulations that include a compound of any of Formula (I)-(XXIIIh), suitable for intramuscular, subcutaneous, or intravenous injection may include physiologically acceptable sterile aqueous or non-aqueous solutions, dispersions, suspensions or emulsions, and sterile powders for reconstitution into sterile injectable solutions or dispersions. Examples of suitable aqueous and non-aqueous carriers, diluents, solvents, or vehicles including water, ethanol, polyols (propyleneglycol, polyethylene-glycol, glycerol, cremophor and the like), suitable mixtures thereof, vegetable oils (such as olive oil) and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants. Formulations suitable for subcutaneous injection may also contain additives such as preserving, wetting, emulsifying, and dispensing agents. Prevention of the growth of microorganisms can be ensured by various antibacterial and antifungal agents, such as parabens, chlorobutanol, phenol, sorbic acid, and the like. It may also be desirable to include isotonic agents, such as sugars, sodium chloride, and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the use of agents delaying absorption, such as aluminum monostearate and gelatin.

For intravenous injections, compounds described herein may be formulated in aqueous solutions, preferably in physiologically compatible buffers such as Hank's solution, Ringer's solution, or physiological saline buffer. For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art. For other parenteral injections, appropriate formulations may include aqueous or nonaqueous solutions, preferably with physiologically compatible buffers or excipients. Such excipients are generally known in the art.

Parenteral injections may involve bolus injection or continuous infusion. Formulations for injection may be presented in unit dosage form, e.g., in ampoules or in multi-dose containers, with an added preservative. The pharmaceutical composition described herein may be in a form suitable for parenteral injection as a sterile suspensions, solutions or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents. Pharmaceutical compositions for parenteral administration include aqueous solutions of the active compounds in water-soluble form. Additionally, suspensions of the active compounds may be prepared as appropriate oily injection suspensions. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acid esters, such as ethyl oleate or triglycerides, or liposomes. Aqueous injection suspensions may contain substances which increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol, or dextran. Optionally, the suspension may also contain suitable stabilizers or agents which increase the solubility of the compounds to allow for the preparation of highly concentrated solutions. Alternatively, the active ingredient may be in powder form for constitution with a suitable vehicle, e.g., sterile pyrogen-free water, before use.

Formulations

In certain embodiments, delivery systems for pharmaceutical compounds may be employed, such as, for example, liposomes and emulsions. In certain embodiments, compositions provided herein can also include an mucoadhesive polymer, selected from among, for example, carboxymethylcellulose, carbomer (acrylic acid polymer), poly(methylmethacrylate), polyacrylamide, polycarbophil, acrylic acid/butyl acrylate copolymer, sodium alginate and dextran.

In some embodiments, the compounds described herein may be administered topically and can be formulated into a variety of topically administrable compositions, such as solutions, suspensions, lotions, gels, pastes, medicated sticks, balms, creams or ointments. Such pharmaceutical compounds can contain solubilizers, stabilizers, tonicity enhancing agents, buffers and preservatives.

The compounds described herein may also be formulated in rectal compositions such as enemas, rectal gels, rectal foams, rectal aerosols, suppositories, jelly suppositories, or retention enemas, containing conventional suppository bases such as cocoa butter or other glycerides, as well as synthetic polymers such as polyvinylpyrrolidone, PEG, and the like. In suppository forms of the compositions, a low-melting wax such as, but not limited to, a mixture of fatty acid glycerides, optionally in combination with cocoa butter is first melted.

Examples of Methods of Dosing and Treatment Regimens

The compounds described herein can be used in the preparation of medicaments for the inhibition of menin or a homolog thereof, or for the treatment of diseases or conditions that would benefit, at least in part, from inhibition of menin or a homolog thereof. In addition, a method for treating any of the diseases or conditions described herein in a subject in need of such treatment, involves administration of pharmaceutical compositions containing at least one compound of any of Formula (I)-(XXIIIh), described herein, or a pharmaceutically acceptable salt, pharmaceutically acceptable N-oxide, pharmaceutically active metabolite, pharmaceutically acceptable prodrug, or pharmaceutically acceptable solvate thereof, in therapeutically effective amounts to said subject.

The compositions containing the compound(s) described herein can be administered for prophylactic and/or therapeutic treatments. In therapeutic applications, the compositions are administered to a patient already suffering from a disease or condition, in an amount sufficient to cure or at least partially arrest the symptoms of the disease or condition. Amounts effective for this use will depend on the severity and course of the disease or condition, previous therapy, the patient's health status, weight, and response to the drugs, and the judgment of the treating physician. It is considered well within the skill of the art for one to determine such therapeutically effective amounts by routine experimentation (including, but not limited to, a dose escalation clinical trial).

In prophylactic applications, compositions containing the compounds described herein are administered to a patient susceptible to or otherwise at risk of a particular disease, disorder or condition. Such an amount is defined to be a “prophylactically effective amount or dose.” In this use, the precise amounts also depend on the patient's state of health, weight, and the like. It is considered well within the skill of the art for one to determine such prophylactically effective amounts by routine experimentation (e.g., a dose escalation clinical trial). When used in a patient, effective amounts for this use will depend on the severity and course of the disease, disorder or condition, previous therapy, the patient's health status and response to the drugs, and the judgment of the treating physician.

In the case wherein the patient's condition does not improve, upon the doctor's discretion the administration of the compounds may be administered chronically, that is, for an extended period of time, including throughout the duration of the patient's life in order to ameliorate or otherwise control or limit the symptoms of the patient's disease or condition.

In the case wherein the patient's status does improve, upon the doctor's discretion the administration of the compounds may be given continuously; alternatively, the dose of drug being administered may be temporarily reduced or temporarily suspended for a certain length of time (i.e., a “drug holiday”). The length of the drug holiday can vary between 2 days and 1 year, including by way of example only, 2 days, 3 days, 4 days, 5 days, 6 days, 7 days, 10 days, 12 days, 15 days, 20 days, 28 days, 35 days, 50 days, 70 days, 100 days, 120 days, 150 days, 180 days, 200 days, 250 days, 280 days, 300 days, 320 days, 350 days, or 365 days. The dose reduction during a drug holiday may be from 10%-100%, including, by way of example only, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 100%.

Once improvement of the patient's conditions has occurred, a maintenance dose is administered if necessary. Subsequently, the dosage or the frequency of administration, or both, can be reduced, as a function of the symptoms, to a level at which the improved disease, disorder or condition is retained. Patients can, however, require intermittent treatment on a long-term basis upon any recurrence of symptoms.

The amount of a given agent that will correspond to such an amount will vary depending upon factors such as the particular compound, disease or condition and its severity, the identity (e.g., weight) of the subject or host in need of treatment, but can nevertheless be routinely determined in a manner known in the art according to the particular circumstances surrounding the case, including, e.g., the specific agent being administered, the route of administration, the condition being treated, and the subject or host being treated. In general, however, doses employed for adult human treatment will typically be in the range of 0.02-5000 mg per day, or from about 1-1500 mg per day. The desired dose may conveniently be presented in a single dose or as divided doses administered simultaneously (or over a short period of time) or at appropriate intervals, for example as two, three, four or more sub-doses per day.

The pharmaceutical composition described herein may be in unit dosage forms suitable for single administration of precise dosages. In unit dosage form, the formulation is divided into unit doses containing appropriate quantities of one or more compound. The unit dosage may be in the form of a package containing discrete quantities of the formulation. Non-limiting examples are packaged tablets or capsules, and powders in vials or ampoules. Aqueous suspension compositions can be packaged in single-dose non-reclosable containers. Alternatively, multiple-dose reclosable containers can be used, in which case it is typical to include a preservative in the composition. By way of example only, formulations for parenteral injection may be presented in unit dosage form, which include, but are not limited to ampoules, or in multi-dose containers, with an added preservative.

The foregoing ranges are merely suggestive, as the number of variables in regard to an individual treatment regime is large, and considerable excursions from these recommended values are not uncommon. Such dosages may be altered depending on a number of variables, not limited to the activity of the compound used, the disease or condition to be treated, the mode of administration, the requirements of the individual subject, the severity of the disease or condition being treated, and the judgment of the practitioner.

Toxicity and therapeutic efficacy of such therapeutic regimens can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, including, but not limited to, the determination of the LD₅₀ (the dose lethal to 50% of the population) and the ED₅₀ (the dose therapeutically effective in 50% of the population). The dose ratio between the toxic and therapeutic effects is the therapeutic index and it can be expressed as the ratio between LD₅₀ and ED₅₀. Compounds exhibiting high therapeutic indices are preferred. The data obtained from cell culture assays and animal studies can be used in formulating a range of dosage for use in human. The dosage of such compounds lies preferably within a range of circulating concentrations that include the ED₅₀ with minimal toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized.

Combination Treatments

The Menin-MLL inhibitor compositions described herein can also be used in combination with other well known therapeutic reagents that are selected for their therapeutic value for the condition to be treated. In general, the compositions described herein and, in embodiments where combinational therapy is employed, other agents do not have to be administered in the same pharmaceutical composition, and may, because of different physical and chemical characteristics, have to be administered by different routes. The determination of the mode of administration and the advisability of administration, where possible, in the same pharmaceutical composition, is well within the knowledge of the skilled clinician. The initial administration can be made according to established protocols known in the art, and then, based upon the observed effects, the dosage, modes of administration and times of administration can be modified by the skilled clinician.

In certain instances, it may be appropriate to administer at least one Menin-MLL inhibitor compound described herein in combination with another therapeutic agent. By way of example only, if one of the side effects experienced by a patient upon receiving one of the Menin-MLL inhibitor compounds described herein is nausea, then it may be appropriate to administer an anti-nausea agent in combination with the initial therapeutic agent. Or, by way of example only, the therapeutic effectiveness of one of the compounds described herein may be enhanced by administration of an adjuvant (i.e., by itself the adjuvant may have minimal therapeutic benefit, but in combination with another therapeutic agent, the overall therapeutic benefit to the patient is enhanced). Or, by way of example only, the benefit experienced by a patient may be increased by administering one of the compounds described herein with another therapeutic agent (which also includes a therapeutic regimen) that also has therapeutic benefit. In any case, regardless of the disease, disorder or condition being treated, the overall benefit experienced by the patient may simply be additive of the two therapeutic agents or the patient may experience a synergistic benefit.

The particular choice of compounds used will depend upon the diagnosis of the attending physicians and their judgment of the condition of the patient and the appropriate treatment protocol. The compounds may be administered concurrently (e.g., simultaneously, essentially simultaneously or within the same treatment protocol) or sequentially, depending upon the nature of the disease, disorder, or condition, the condition of the patient, and the actual choice of compounds used. The determination of the order of administration, and the number of repetitions of administration of each therapeutic agent during a treatment protocol, is well within the knowledge of the skilled physician after evaluation of the disease being treated and the condition of the patient.

It is known to those of skill in the art that therapeutically-effective dosages can vary when the drugs are used in treatment combinations. Methods for experimentally determining therapeutically-effective dosages of drugs and other agents for use in combination treatment regimens are described in the literature. For example, the use of metronomic dosing, i.e., providing more frequent, lower doses in order to minimize toxic side effects, has been described extensively in the literature Combination treatment further includes periodic treatments that start and stop at various times to assist with the clinical management of the patient.

For combination therapies described herein, dosages of the co-administered compounds will of course vary depending on the type of co-drug employed, on the specific drug employed, on the disease or condition being treated and so forth. In addition, when co-administered with one or more biologically active agents, the compound provided herein may be administered either simultaneously with the biologically active agent(s), or sequentially. If administered sequentially, the attending physician will decide on the appropriate sequence of administering protein in combination with the biologically active agent(s).

In any case, the multiple therapeutic agents (one of which is a compound of Formula (I)-(XXIIIh), described herein) may be administered in any order or even simultaneously. If simultaneously, the multiple therapeutic agents may be provided in a single, unified form, or in multiple forms (by way of example only, either as a single pill or as two separate pills). One of the therapeutic agents may be given in multiple doses, or both may be given as multiple doses. If not simultaneous, the timing between the multiple doses may vary from more than zero weeks to less than four weeks. In addition, the combination methods, compositions and formulations are not to be limited to the use of only two agents; the use of multiple therapeutic combinations are also envisioned.

It is understood that the dosage regimen to treat, prevent, or ameliorate the condition(s) for which relief is sought, can be modified in accordance with a variety of factors. These factors include the disorder from which the subject suffers, as well as the age, weight, sex, diet, and medical condition of the subject. Thus, the dosage regimen actually employed can vary widely and therefore can deviate from the dosage regimens set forth herein.

The pharmaceutical agents which make up the combination therapy disclosed herein may be a combined dosage form or in separate dosage forms intended for substantially simultaneous administration. The pharmaceutical agents that make up the combination therapy may also be administered sequentially, with either therapeutic compound being administered by a regimen calling for two-step administration. The two-step administration regimen may call for sequential administration of the active agents or spaced-apart administration of the separate active agents. The time period between the multiple administration steps may range from, a few minutes to several hours, depending upon the properties of each pharmaceutical agent, such as potency, solubility, bioavailability, plasma half-life and kinetic profile of the pharmaceutical agent. Circadian variation of the target molecule concentration may also determine the optimal dose interval.

In addition, the compounds described herein also may be used in combination with procedures that may provide additional or synergistic benefit to the patient. By way of example only, patients are expected to find therapeutic and/or prophylactic benefit in the methods described herein, wherein pharmaceutical composition of a compound disclosed herein and/or combinations with other therapeutics are combined with genetic testing to determine whether that individual is a carrier of a mutant gene that is known to be correlated with certain diseases or conditions.

The compounds described herein and combination therapies can be administered before, during or after the occurrence of a disease or condition, and the timing of administering the composition containing a compound can vary. Thus, for example, the compounds can be used as a prophylactic and can be administered continuously to subjects with a propensity to develop conditions or diseases in order to prevent the occurrence of the disease or condition. The compounds and compositions can be administered to a subject during or as soon as possible after the onset of the symptoms. The administration of the compounds can be initiated within the first 48 hours of the onset of the symptoms, within the first 6 hours of the onset of the symptoms, or within 3 hours of the onset of the symptoms. The initial administration can be via any route practical, such as, for example, an intravenous injection, a bolus injection, infusion over 5 minutes to about 5 hours, a pill, a capsule, transdermal patch, buccal delivery, and the like, or combination thereof. A compound should be administered as soon as is practicable after the onset of a disease or condition is detected or suspected, and for a length of time necessary for the treatment of the disease, such as, for example, from about 1 month to about 3 months. The length of treatment can vary for each subject, and the length can be determined using the known criteria. For example, the compound or a formulation containing the compound can be administered for at least 2 weeks, between about 1 month to about 5 years, or from about 1 month to about 3 years.

Example 101a: Menin-MLL In Vitro Inhibitory Activity

The menin-MLL IC₅₀s of compounds disclosed herein is determined as described below.

Cell Preparation:

The MLL-rearranged MOLM13 cell line and the MLL-germline cell line HL60 growing in log phase cultures was counted and re-suspended at a concentration of 10,000 cells/soul (100,000 cells/ml) in RPMI 10% FBS containing medium with Pen/Strep.

A total of 100 uls were plated in each well of a round-bottom 96 well non-tissue treated plate (Corning). Thus, each well had 10,000 MOLM13 or HiL60 cells on day.

Compound Dilution:

Each compound was diluted to a final concentration of 5 mM in DMSO. 15 ml Falcon tubes were used for making the dilution. These 5 mM stocks were stored in 2 ml light-protective Eppendorf tubes in multiple 50 ul aliquots to prevent repeated freeze-thaw of the entire stock.

The following concentrations were decided for each compound: 0.01 μM, 0.03 μM, 0.1 μM, 0.3 μM, 0.5 μM, 1 μM, 3 μM, and 5 μM.

First, 2× working stocks for each desired concentration were made using using the standard RPMI 10% FBS medium as the diluent.

Specifically, working stocks of 0.02 μM, 0.06 μM, 0.2 μM, 0.6 μM, 1 μM, 2 μM, 6 μM and 10 μM (2× of the desired concentrations mentioned above) were made from the 5 mM stock (see note at the bottom for more details).

100 μl of each working stock dilution was added to the respective well containing 100 μl of plated cells, thereby achieving a 1×drug concentration. A similar strategy was used for the DMSO control arm.

Proliferation Assays:

Proliferation is measured using the BD Fortes' flow cytometry machine and FACS Diva software. Total numbers of live cells are measured by staining cells with a dead cell stain such as Sytox. Cells are re-planted every 3-4 days and counting is performed on days 3, 7 and 10 or 3, 6 and 9. Differentiation of cells is measured using CD11b as a marker of monocytic differentiation.

Note:

To minimize inaccuracies, once a stock of higher concentration was made, 10 fold dilutions were made from that working stock. Eg: first the 10 μM 2× working stock was made by adding 4 μM of the 5 mM drug to 2 mL of medium. From this, the 1 μM and 0.1 working stocks were made by vortexing the 10 μM stock vigorously and adding 90 μL of this to 810 μL of medium (1:10 dilution). Subsequently, a similar 1:10 dilution of the 1 μM stock (90 μL, 1 μM stock+810 μL medium) gave a 0.1 μM working stock. In this way, 2× working stocks of 0.02 μM, 0.06 μM, 0.1 μM, 0.2 μM, 0.6 μM, 1 μM, 2 μM and 10 μM were made.

The IC₅₀ s menin-MLL inhibition are determined using methods known to one skilled in the art.

Long Term Proliferation Assay Protocol

-   -   1) On Day 0, in a flat bottom 96-well plate, add 100 μL of cells         per well at the densities optimized.     -   2) Prepare compounds in DMSO at 500× final concentration. Dilute         the compounds with DMSO at the dilution.     -   3) Dilute the compounds in media at 3× final concentration. Add         50 μL of compound or DMSO at 3× final concentration to each         well. Final volume in each well is 150 μL, and final         concentration of DMSO is 0.2%. Also include 3 untreated control         wells, by adding 50 μL of media alone.     -   4) Incubate plates for 96 hours.     -   5) Count the cells using the Acumen, with capabilities for         96-well plates. Pipette cells up and down to mix in each well,         and add desired volume of cells to a new flat bottom         poly-D-lysine 96-well plate. Add Calcein AM at 1 μM final         concentration. Let cells sit at RT for 10 mins followed by a         quick spin to get cells settled on the bottom of the wells.         Incubate the plate for additional 40 mins in the incubator. Take         out the plate and read by Acumen. Calculate the cell numbers         taken into account the dilution factors.     -   6) Split the master plate. To do this take the total viable cell         count calculated using step 5). Take the average of the         replicates for each dose in order to be used in splitting the         cells.     -   7) Use a 96 well V-bottom plate to spin down the cells to remove         old media and compound to split the cells. Based on the split         ratio place the proper amount of media and cells into the         V-bottom plate, and spin the plate at 1100 rpm for 5 minutes.     -   8) Following the spin remove the media, careful not to disturb         the cellpellet.     -   9) Re-suspend pellet in 100 μL fresh media, and add to a new         96-well flat bottom plate.     -   10) Add fresh compound, in the same manner as Step 3).     -   11) Incubate plates for 72 hours. Repeat steps 5)-10) on Day 7.     -   12) Incubate plates for 96 hours. Repeat Step 5)-10) on Day 11.     -   13) Incubate 72 hours and repeat step 5) to take a final count.     -   14) Data Analysis

To calculate growth for days 4, 7, 11, and 14:

-   -   Calculate the split factor for day 4 to 7, day 7 to 11, and day         11-14. The split factor is the viable cells/mL on Day X (either         4, 7 or 11) divided by the density the cells are being split         back to.     -   For growth of cells from day 4 to 7, multiply the day 7 viable         cells/mL density by the split factor from day 4.     -   For growth of cells from day 7 to 11, multiply the day 11 viable         cells/mL density by the days 4, and 7 split factors.     -   For growth of cells from Day 11 to 14, multiply the Day 14         viable cells/mL density by the days 4, 7, and 11 split factors.     -   Plot growth on semi-log chart (viable cells/mL on Y axis, in         log, and days on X axis).     -   The growth inhibition was calculated with the formula         ((untreated cell numbers−treated cell numbers)/untreated         cell))).     -   Calculate the IC50 for each compound in each line using XLFit         (Sigmoidal Dose−Response Model,         y=(Bottom+((Top−Bottom)/(1+((IC50/x){circumflex over         ( )}Hill))))).         Results:

The IC₅₀ graphs of menin-MLL inhibition for Compound 2 in various cell lines along with the comparison with a known menin-MLL inhibitor MI-503 (Borkin et al. 2015, Cancer Cell 27, 589-602) are depicted in FIGS. 1-4.

Example 102: Proliferation Study in MLL-Leukemia Cells

Introduction and Rationale

The objective of the study was to evaluate the ability of representative compounds of the present invention, inhibitors of Menin/MLL interaction to inhibit cell proliferation. The proliferation inhibitory effect was investigated in two human MLL-leukemia cells selected on the bases of MLL fusion protein and listed in Table 102. HL-60 cell line was used as negative control.

TABLE 102 Human MLL-leukemia cells Cell Type MLL gene fusion MV-4-11 MLL-AF4 MOLM-13 MLL-AF9

ATP is present in all metabolically active cells and is considered as a marker for cell viability and proliferation. The metabolic cell activity was determined using the CellTiter-Glo kit from Promega, an ATP monitoring system based on the production of luminescence by the reaction of ATP with added UltraGlo® recombinant luciferase (Kawano et al., 2016), according to the supplier's experimental recommendations.

Experimental Design

The described assay evaluates the ability of 4 representative compounds to inhibit the cell proliferation in the human MLL-leukemia cells plus a negative control cell line.

The assay provides potency values (IC₅₀) for each test compound at a single time point Day 4 (T4).

Seven concentrations of the compounds (2.00E−05-6.67E−06-2.22E−06-7.41E−07-2.47E−07-8.23E−08-2.74E−08M), were assessed in duplicate in an individual test occasion in all the cell lines. MI-503 (Borkin et al., 2015) was used as reference compound and was tested at the same concentrations as the NCEs. 100% of proliferation is represented by the untreated cells (0.2% DMSO). The cell growth was monitored up to 4 days in culture.

Materials and Methods

Cell Culture

MV4-11, MOLM-13 and HL-60 cells (see Table 2) were maintained in RPMI-1640 medium (Invitrogen, Cat. n. 618700, Batch n. 1965930) supplemented with 10% of Heat Inactivated FBS (Invitrogen, Cat n. 10500, Batch n. 08Q8078K) and 1% Pen-Strep (Invitrogen, Cat. N. 15140, Batch n. 1910859) and cultured at 37° C. in a humidified incubator with 5% CO₂.

All the cell lines grow in suspension and the cell density was maintained in a range of 2×10⁵-1×10⁶ viable cells/ml. Cells were pelleted at 130 g×5 min and conditioned medium was used to dilute the cell suspension.

Test items were dissolved in glass vials at 10 mM in DMSO with purity ≥99.9% (Sigma, D8418, batch n. SHBH4245V) and stored at −20° C. in 1.5 mL Eppendorf tubes.

Compound Plate Preparation

Serial dilutions 1 to 3 in DMSO 100% were prepared starting from a 10 mM stock solutions to generate 7 points concentration response curve (CRC).

For each plate to test, one 0.4 μL copy plate and four 0.3 μL copy plates were then stamped into 96-well plates not treated for cell adhesion (Sarstedt—cat.no. 82.1581.001) by acoustic liquid Handling, Echo, at a concentration which was 500 fold the final assay concentration. Stamped plates were stored at −20° C. The final concentrations for the reference compound, MI-503, and the test items were: 2.00E−05, 6.67E−06, 2.22E−06, 7.41E−07, 2.47E−07, 8.23E−08 and 2.74E−08 M.

Long-Term Proliferation Assay Procedure

Cells were plated in 96-well flat bottom microtiter plates at cell density of 15,000 cells/ml for HL-60, 1000 cells/ml for MOLM-13 and 10,000 cell/ml for MV4-11. Cells were treated with 0.2% DMSO (Sigma, D8418, batch n. SHBH4245V) or serial dilutions of compounds (0.027 μM-20 μM) in DMSO (0.2% final concentration). Cells were incubated in a 5% CO₂ incubator at 37° C. for 4 days. A CellTiterGlo viability assay (Promega) was employed.

Luminescence was read by using VictorV (Perkin Elmer) multilabel plate reader using the standard protocol for luminescence in 96 well plate. The experiment was performed in duplicate.

Data Handling and Analysis

Data were expressed as % of inhibition compared to the 0.2% DMSO negative control, and was calculated as follows: % inhibition=100−[(RLU sample)×100/(RLU average controls*)] *cells containing 0.2% DMSO

CRCs were analysed by GraphPad and IC₅₀ values were calculated by non-linear regression using 4 parameter-logistic equation. IC₅₀ (μM) values were reported in the final data table. The curve fittings were performed leaving free all the parameters. Any constrain were reported in the results table.

Results

After visual inspection no solubility issues were observed for all the compounds tested.

Increasing concentrations of MI-503 inhibited cell viability in a concentration dependent manner in all the cell lines treated with IC₅₀ values of 0.42 μM in HL-60, 0.19 μM in MV4-11 and 0.23 μM in MOLM-13 (FIG. 5, FIG. 6 and FIG. 7).

As shown in Table 104, Compound 10 and Compound 11 inhibited the viability of MV4-11 and MOLM-13 with IC50 value of 0.22 μM and 0.2 μM, respectively in MV4-11 and 0.31 μM and 0.26 μM, respectively in MOLM-13. A similar effect was observed for both compounds in HL-60 cells with an IC50 of 0.36 μM for Compound 10 and 0.51 μM for Compound 11.

Also increasing concentrations of Compound 13 inhibited the cell viability of MV4-11 and MOLM-13 cells with IC₅₀ values of 0.91 μM and 1.23 μM, respectively. In HL-60, Compound 13 is slightly less potent with IC₅₀ of 2.75 μM (FIG. 5, FIG. 6 and FIG. 7).

Compound 12 is not active up to the highest concentration tested in HL-60; slightly active in MOLM-13 cells with a maximal inhibition of about 40% and active in MV4-11 with an IC50 of 0.43 μM and a maximal inhibition of 89% (FIG. 5, FIG. 6 and FIG. 7).

Results

Cell Growth Curves

Cell growth curves were plotted as described in the experimental design session and reported in Appendix 1.

MOLM-13 and MV4-11 cells grew exponentially along the 14 days in culture with a growth rate cell type dependent.

HL-60 cells grew in an exponential manner up to 11 day in culture in both the experiments. A growth slowdown was observed between T11 and T14.

RS4; 11 cells showed a slow growth profile up to 7 days in culture followed by a progressive decrease of growth with a significant signal reduction at T14. At T14 the cell viability was very low close to the lower detection limit with the absence of a workable signal window. The data obtained at this time point (T14) were excluded from the data analysis.

Cell Proliferation Inhibition

A visual inspection of treated wells was carried out along the entire period of the treatment to assess whether compound precipitation occurred. No solubility issues were observed for any compound tested.

The effect of test substances to inhibit cell proliferation at different end points is summarized in FIG. 8. pIC₅₀, IC₅₀, slope and % maximal effect at the highest tested concentration are reported.

MI-503—Increasing concentrations of MI-503 fully inhibited cell viability in a concentration dependent manner in all the cell lines treated with IC₅₀ values reported in FIG. 8.

COMPOUND 11—Compound 11 fully inhibited cell viability in a concentration dependent manner with similar potency values in all the cell lines tested. A slight increase in potency along the time in culture was observed.

COMPOUND 12—At T4, increasing conc. of Compound 12 fully inhibited the cell viability of RS4; 11 cells. A partial effect was observed for MV4-11 and MOLM-13. No activity was observed in HL-60 up to the maximal conc. tested. The compound profile was confirmed more or less in all the time points with a weak leftward shift of the potency along the time in culture.
